CXC A4/U2/21 www.cxc.org Introduction T he Caribbean Advanced Proficiency Examination® (CAPE®) is designed to provide certification of the academic, vocational and technical achievement of students in the Caribbean who, having completed a minimum of five years of secondary education, wish to further their studies. The examinations address the skills and knowledge acquired by students under a flexible and articulated system where subjects are organised in 1-Unit or 2-Unit courses with each Unit containing three Modules. Subjects examined under CAPE® may be studied concurrently or singly. The Caribbean Examinations Council offers three types of certification at the CAPE® level. The first is the award of a certificate showing each CAPE® Unit completed. The second is the CAPE® Diploma, awarded to candidates who have satisfactorily completed at least six Units, including Caribbean Studies. The third is the CXC® Associate Degree, awarded for the satisfactory completion of a prescribed cluster of ten CAPE® Units including Caribbean Studies, Communication Studies and Integrated Mathematics. Integrated Mathematics is not a requirement for the CXC® Associate Degree in Mathematics. The complete list of Associate Degrees may be found in the CXC® Associate Degree Handbook. For the CAPE® Diploma and the CXC® Associate Degree, candidates must complete the cluster of required Units within a maximum period of five years. To be eligible for a CXC® Associate Degree, the educational institution presenting the candidates for the award, must select the Associate Degr ee of choice at the time of registration at the sitting (year) the candidates are expected to qualify for the award. Candidates will not be awarded an Associate Degree for which they were not registered. CXC A4/U2/21 www.cxc.org Information Technology Syllabus RATIONALE The Information Technology Syllabus for the Caribbean Advanced Proficiency Examination (CAPE®) reflects the belief that Information Technology is essential to the economic and social development of the region. The widespread use of Information Technology, the tools and techniques for inputting, processing, storing, outputting, transmitting and receiving information, which was made possible because of improvements in computer and telecommunications technology, has significantly changed society. An interestingly large proportion of business transactions is now performed over computer networks. The Internet and multimedia computers have had a significant impact on the ways in which people work, learn, communicate, conduct business, and seek entertainment. The increased integration of computer and telecommunications technology has led to an increased globalisation of the world economy, evident in greater individual, corporate and transnational trade activities; movement of finance, and access to market. Moreover, as the world becomes increasingly involved in the practice of technology, the activities which were once thought of as far-fetched are becoming more routine. Consequently, there is a heightened awareness of the role of technology in solving problems. This wide spread use of technology implies that we must know how to use the technology, not only from a purely technical point of view, but it also means that we must be conscious of the impact of Information Technology. In particular, we must be made aware that the appropriate use of Information Technology can help solve the problems that we are facing in our daily lives, whether they be of an economic, social or personal nature, and that Information Technology provides opportunities for economic development, as well as for further integration of the region. However, the misuse of Information Technology also raises a number of ethical, legal and political issues, ranging from questions concerning privacy of information about individuals, to intellectual property rights. This course, through authentic, learner-centred teaching and assessment approaches, presents students with advanced ideas in the Information Technology and allied fields, including the practices and implications for using technology in everyday activities. In keeping with the UNESCO Pillars of Learning, this course of study will contribute to the development of a person who will learn to be, learn to know, learn to do, learn to live together, and learn to transform oneself and society. In order for the Caribbean to effectively increase its participation in the information economies and societies, it is essential that Caribbean people become familiar with this technology. The Information Technology syllabus is based on objectives, skills and content which will cultivate the attributes of the Ideal Caribbean Person as articulated by CARICOM. That is, a Caribbean person who demonstrates multiple literacies, as well as independent and critical thinking, and questions the beliefs and practices of the past and brings this to bear on the innovative application of science and technology to problem-solving. Such a person will inevitably demonstrate a high level of self-confidence and self-esteem, a positive work ethic, and display and nurture creative imagination in the economic and entrepreneurial spheres and other areas of life. Consequently, students who pursue this course of study will develop critical skills and competencies, including, communicative, collaborative and creative skills. CXC A4/U2/21 1 www.cxc.org AIMS The syllabus aims to: 1. develop an awareness of the importance of information in the solution of many problems; 2. develop an awareness of the importance of using reliable and ethical information sources and services; 3. develop an awareness of the nature and sources of information and objective measures to gathering and processing information; 4. understand the importance of critically evaluating data in the production of information; 5. develop an understanding of users, hardware, software, networks, databases and information systems and their uses; 6. develop an awareness of the history and importance of Information Technology; 7. develop an awareness of the cultural, ethical, legal and political considerations associated with Information Technology; 8. develop competence in solving real-life problems, using the tools and techniques of the computer and computer-related technologies; 9. develop an appreciation of emerging and innovative technologies that are designed to improve performance and solve problems; 10. develop creative, collaborative, communicative and critical thinking skills using appropriate Information and Communication Technologies (ICTs); and, 11. prepare students for tertiary level studies and employment in technology-oriented professions. SKILLS AND ABILITIES TO BE ASSESSED The skills that students are expected to have developed on completion of this syllabus have been grouped under three headings: 1. Knowledge and Comprehension; 2. Application and Analysis; and, 3. Synthesis and Evaluation. CXC A4/U2/21 2 www.cxc.org Knowledge and Comprehension The ability to: - recall and grasp the meaning of basic facts, concepts and principles of Information Technology; - identify real-life problems for which Information Technology solutions are appropriate and beneficial; and, - assess Information Technology usage patterns to establish legal compliance, ethical and cultural suitability. Application and Analysis The ability to: - use facts, concepts, principles and procedures in unfamiliar situations; - identify and recognise the relationships among the various components of Information Technology and their impact on society; and, - recognise the limitations and assumptions of data gathered in an attempt to solve a problem. Synthesis and Evaluation The ability to: - make reasoned judgements and recommendations based on the value of ideas and information and their implications; - use the computer and computer-based tools to solve problems; and, - justify and apply appropriate techniques to the principles of problem-solving. PREREQUISITES OF THE SYLLABUS Any person with a good grasp of the Caribbean Secondary Education Certificate (CSEC®) Information Technology Syllabus, or its equivalent, should be able to pursue the course of study defined by this syllabus.

Have students identify the information component in each scenario. 3. Organise field trips to business places for students to observe how Information Technology is used to address problems faced by the organisation. 4. Invite professionals, artists, and others to make presentations to students to give additional perspectives on issues relevant to their studies. Encourage students to make presentations to persons outside of the school system, who can evaluate or comment on the presentations as well as answer the students’ questions. 5. Use a physical activity, such as a sport, to demonstrate how the use of information can be an effective tool or mechanism in ensuring a desired outcome, such as improved performance or success over competitors. Students could also view a video of an athlete sharing their game plan that assured their success after the event. 6. Develop a set of scenarios in which there are either opportunities or problems encountered by an organisation. Students are required to (a) identify a problem, (b) formulate a problem statement, (c) suggest two possible solutions, and (d) recommend one of the solutions and justify the choice. CXC A4/U2/21 16 www.cxc.org UNIT 1 MODULE 3: INFORMATION AND PROBLEM-SOLVING (cont’d) 7. Adopt a single DFD notation style and have students complete several exercises to become familiar with that style, for example, Gane and Sarson. Present data flow diagramming errors and have students label these with the relevant terms. For example, black hole - process with only input data flow, a process with only output data flow from it; data stores or external entities that are connected directly to each other, in any combination; incorrectly labelling data flow or objects, some examples are: (a) (b) (c) 8. labels omitted from data flow or objects; data flow labelled with a verb; and, processes labelled with a noun. Work in groups to address problem-solving through the development of algorithms and the use of pseudocode to solve those problems. This activity should ensure that all elements are practiced.

Candidates will be expected to answer all questions (50%) Paper 032 (1 hour, 30 minutes) SCHOOL-BASED ASSESSMENT (20 %) (20%) Paper 031 This paper consists of a project. Unit 1: Information Technology Theory The aim of the project is to develop candidates’ appreciation for and use of the problem-solving process. Requirements Candidates are required to identify and examine a problem in their own environment which requires an Information Technology based solution. Candidates should define the problem, collect data relevant to that problem, identify and examine options and present the selected solution with justification. The candidates should ensure that the selected solution is an Information Technology based solution. The student should produce a report of no more than 1500 words. Students are encouraged to work in groups. Unit 2: Application and Implications The aim of the project is to provide opportunity for the candidates to demonstrate proficiency in the use of Information Technology tools to solve real-life problems and have an appreciation for the factors that mitigate against and manage risk associated with Information Technology. Requirements Candidates are expected to implement an Information Technology based solution, which should include either a database or a website, to an identified problem in their environment and present that CXC A4/U2/21 28 www.cxc.org solution using appropriate productivity tools and/or web pages. The project should also include a report of approximately 600–700 words which outlines the problem and addresses any implications which may arise from the implementation of the solution. MODERATION OF SCHOOL-BASED ASSESSMENT A School-Based Assessment Record Sheet will be sent each year to schools submitting students for the examinations. All School-Based Assessment Record Sheets must be submitted online using the SBA data capture module of the Online Registration System (ORS). A sample of assignments will be requested by CXC® for moderation purposes. This sample must be electronically submitted. These samples will be reassessed by CXC® Examiners who moderate the School-Based Assessment. Teachers’ marks may be adjusted as a result of moderation. The Examiners’ comments will be sent to schools. Copies of the students’ submissions must be retained by the school until three months after publication by CXC® of the examination results. ASSESSMENT DETAILS External Assessment Paper 01, Paper 02 and Paper 032 The external assessment consists of written papers. They are externally set and externally assessed. Together the Paper 01 and 02 contribute 80 per cent, and the Paper 032 contributes 20 per cent of of the final mark. Paper 01 (1 hour 30 minutes) 1. Composition of the Paper The paper will consist of 45 multiple-choice items, 15 from each Module. All questions are compulsory and knowledge of the entire Syllabus is expected.

Award of marks Marks will be awarded for knowledge and comprehension, application and analysis and synthesis and evaluation. School-Based Assessment (20% of Total Assessment) School-Based Assessment is an integral part of student assessment in the course covered by this syllabus. It is intended to assist students in acquiring certain knowledge, skills and attitudes that are associated with the subject. The activities for the School-Based Assessment are linked to the syllabus and should form part of the learning activities to enable the student to achieve the objectives of the syllabus. Students are encouraged to work in groups. During the course of study for the subject, students obtain marks for the competence they develop and demonstrate in undertaking their School-Based Assessment assignments. These marks contribute to the final marks and grades that are awarded to students for their performance in the examination. The guidelines provided in this syllabus for selecting appropriate tasks are intended to assist teachers and students in selecting assignments that are valid for the purpose of School-Based Assessment. The guidelines provided for the assessment of these assignments are intended to assist teachers in CXC A4/U2/21 30 www.cxc.org awarding marks that are reliable estimates of the achievement of students in the School-Based Assessment component of the course. In order to ensure that the scores awarded by the teachers are not out of line with the CXC® standards, the Council undertakes the moderation of a sample of the School-Based Assessment assignments marked by each teacher. School-Based Assessment provides an opportunity to individualise a part of the curriculum to meet the needs of students. It facilitates feedback to the student at various stages of the experience. This helps to build the self-confidence of students as they proceed with their studies. School-Based Assessment also facilitates the development of critical skills and ability emphasised by this CAPE® subject and enhances the validity of the examination on which candidate performance is reported. School-Based Assessment, therefore, makes a significant and unique contribution to both the development of relevant skills and the testing and rewarding of students for the development of those skills. The Caribbean Examinations Council seeks to ensure that the School-Based Assessment scores are valid and reliable estimates of accomplishment. The guidelines provided in this syllabus are intended to assist in doing so. Candidates’ total School-Based Assessment mark for any Unit should be divided in three and allocated to each Module equally. Students are encouraged to work in small groups to complete the SBA. Fractional marks should not be awarded. Wherever the Unit mark is not divisible by three, then: (a) when the remainder is 1 mark, it should be allocated to Module 1; and, (b) when the remainder is 2, one of the marks should be allocated to Module 2 and the other mark to Module 3. 1. Integration of Project into the course 2. (a) The activities related to Project work should be integrated into the course so as to enable candidates to learn and practise the skills of undertaking a successful project. (b) Some time in class should be allocated for general discussion of project work. For example, discussion of how data should be collected, how data should be analysed and how data should be presented. (c) Class time should also be allocated for discussion between teacher and students, and student and student. Management of Project (a) Planning An early start to planning project work is highly recommended and the schedule of the dates for submission should be developed by teachers and candidates. (b) Length The length of the report of the project should be 1500 words for Unit 1 and 600–700 words for Unit 2 excluding diagrams, graphs, tables and bibliographies. (c) Guidance CXC A4/U2/21 31 www.cxc.org Candidates should know the requirements of the project and its assessment process. Although candidates may consult with resource persons besides the teacher the candidate’s submission should be his or her own work. Candidates are not expected to work on their own. The teacher is expected to give appropriate guidance at all stages of project work, for example, chapters to read, alternative procedures to follow and other sources of information. (d) Authenticity Teachers are required to ensure that all projects are the candidates’ work. A recommended procedure is to: (i) engage candidates in discussion; (ii) ask candidates to describe procedures used and summarise findings either orally or written; and, (iii) ask candidates to explain specific aspects of the analysis.

Paper 032 will test the student’s acquisition of the skills in the same areas of the syllabus identified for the School-Based Assessment. Consequently, candidates are advised to respond to three projectbased questions that are similar to the tasks that the school candidates would normally complete and submit for School-Based Assessment. It should be noted that private candidates would not be required to submit a project document. REGULATIONS FOR RESIT CANDIDATES Resit candidates must complete Paper 01 and Paper 02 of the examination for the year for which they reregister. CAPE® candidates may reuse any moderated SBA score within a two-year period. In order to assist candidates in making decisions about whether or not to reuse a moderated SBA score, the Council will continue to indicate on the preliminary results if a candidate’s moderated SBA score is less than 50 per cent in a particular Unit. Candidates reusing SBA scores should register as “Resit candidates” and must provide the previous candidate number when registering. Resit candidates must be entered through a school, approved educational institution or the local Registrar’s office.
